The prayer rope (chotki) is used as a rosary within the Easter Orthodox Church. Buy a 100 knot prayer rope. I suggest getting one with a knotted cross at the end. I use my thumb to move the knots from one to the other.
Preparation
Hold the prayer rope in your left hand, and use your right hand to do the sign of the cross over yourself, saying, “In the name of the Father and of the Son and of the Holy Spirit. Amen.” Then say three times, “Holy God, Holy Mighty, Holy Immortal, have mercy on me.” And finally, pray the “Our Father” (Matthew 6:9-13).
The Jesus Prayer
Then begin saying the Jesus Prayer. Move the first knot with your thumb, saying, “Lord Jesus Christ.” And then move your thumb to the next knot, saying, “have mercy on me.” Repeat 100 times.
You will find three beads on the hundred knot prayer rope. I suggest that you pay them no special attention. They just break the prayer rope up into 25 knot sections. Just say the Jesus Prayer on them.
Conclusion
When you get back to the cross, hold it. And with your right hand again do the sign of the cross, saying: “Glory to the Father, and to the Son, and to the Holy Spirit: as it was in the beginning, is now, and will be for ever. Amen.”
At this point you may wear it around your left wrist or, if you prefer, put it in your pocket so as not to be “seen” (Matt. 6:5-6).
Please note, this is my personal practice. I am not following or representing the Eastern Orthodox practice. You should consult an Orthodox priest if you want to do it “right.’
I highly recommend seeing a spiritual director before beginning any prayer rule. You should consult your priest or pastor. I am sharing my personal practice for those without a spiritual director. Go slowly, stay humble, and be faithful to your church.
